Abstract: The disclosure relates to a method, a system, a computer apparatus, and a storage medium for inspecting an operation period of a valve box. The method for inspecting the operation period of the valve box includes at least one of a pressure of the liquid outlet, a stress of the housing, and an acceleration of the housing is acquired. Single operation periods of the valve box are calculated according to at least one of the pressure of the liquid outlet, the stress of the housing, and the acceleration of the housing. Finally, the single operation periods of the valve box are accumulated to obtain a total operation period of the valve box.
